FP701

FP701 Single Operational Amplifier and Voltage Reference General Description The FP701 is a single chip composed one op-amp (OPA) with a 1.25V precision voltage reference on non-inverting input and an open collector output. It offers space and low cost in many applications such as the secondary feedback control of power supply, AC to DC converter or adaptor. The FP701 is designed to used as OCP detector with few external components. The circuit diagram for typical application example is shown as below.
